A mesoscale convective system formed on the eastern side of Post-Tropical Storm Arthur on June 18th. Favorable low level winds allowed for multiple mini-supercells to form on the leading edge of the mesoscale convective system resulting in a few tornadoes affecting coastal Mississippi. These tornadoes were rated as EF-0 and EF-1 events. A bow echo also developed over coastal Mississippi leading to severe winds and thunderstorm wind damage in the Gulfport-Biloxi metro area. Additionally, the mesoscale convective complex tapped into a region of deep tropical moisture with atmospheric moisture content well above normal levels for mid-June. This resulted in several significant flash flooding events in portions of coastal Mississippi including the city of Picayune. Two fatalities occurred near Picayune where rainfall rates of 2 to 3 inches per hour and QPE of 10 to 15 inches was noted. This very high rainfall total resulted in major flooding on the West Hobolochitto Creek on June 18th and this is where the fatalities occurred. Lingering moisture and weak upper level troughing associated with the slow moving remnants of Post-Tropical Storm Arthur produced additional thunderstorm activity on June 20th. This activity was focused in Biloxi where additional flash flooding occurred.

.UPDATE...
Issued at 354 AM CDT Thu Jun 18 2026
Updated Key Messages for WPC's High Risk of Excessive Rainfall
today for portions of the area. Likely to have a fairly large
stripe of 6 to 10 inch rainfall with isolated totals significantly
higher from Houma and Thibodaux northeastward.
&&
.SHORT TERM...
(Now through Sunday)
Issued at 1220 AM CDT Thu Jun 18 2026
Post Tropical Cyclone Arthur has degenerated to a low pressure
area along the Upper Texas Coast. The remnants will continue to
track across western Louisiana overnight and will reach the
Carolinas coastlines by Friday morning. We've already seen some
rotation in radar data, and expect we'll have short-lived spinups
overnight. Additionally, we remain highly concerned about extreme
rainfall amounts overnight. We already had 2.3 inch precipitable
water values at 00z, with guidance indicating that values near 2.6
inches are possible/likely overnight as a 35-40 knot low level jet
plugs in. The 02Z HRRR, for instance, has a large area of rainfall
totals in excess of 6 inches across the area by mid-afternoon
Thursday with spot totals approaching or exceeding 10 inches. If
these totals, or anything close are realized, we're probably
looking at major flooding in those areas. No changes to Flood
Watch anticipated. Could still be scattered precipitation into
Thursday evening associated with this system before we start
seeing some slight drying.
With precipitable water values remaining near 2 inches through
Sunday, still plenty of moisture available for scattered
convection, even without large scale forcing to aid in producing
lift. The large scale heavy rainfall threat will diminish beyond
Thursday evening, but localized heavy rain still possible. Could
also see a few microbursts on Friday.
A second issue over the weekend will be heat stress. We'll likely
see at least some sunshine at times Friday through the weekend
that will allow temperatures to get into the lower, or possibly
middle 90s in many areas. With dew points likely in the upper 70s
to near 80, and lots of residual moisture on the ground, it's
going to be steamy. Likely to have heat index values near our 108
degree criteria for Heat Advisories in many areas on Friday and
possibly again on Sunday. This will be addressed once we get past
the rainfall and tornado issues this morning. Overnight lows may
have trouble getting below 80 degrees for several nights.
&&
.LONG TERM...
(Sunday night through Wednesday)
Issued at 1220 AM CDT Thu Jun 18 2026
Ridging sets up over the northern Gulf for the first half of next
week. However, shortwaves will be tracking west to east just north
of the local area. If we are going to have a day that is
completely dry, it'll probably be Monday. Similar to the weekend,
we'll have to monitor for potential Heat Advisories, especially
Monday. For Tuesday and Wednesday, the question will be exactly
when storms develop. If they develop early enough in the day, that
would blunt the heat somewhat. For now, will stick with the NBM
forecast temperatures with several days seeing highs in the lower
and middle 90s.

.AVIATION...
(12Z TAFS)
Issued at 613 AM CDT Thu Jun 18 2026
Large area of SHRA/TSRA moving across most terminals early this
morning with IFR or lower conditions. Main exceptions are KHUM and
KBTR, where convection has moved east for now. Eastern terminals
could still see gusts to around 40 knots as convection moves
through. The current area of convection should be east of all
terminals by 18z, but with abundant moisture still in place,
afternoon heating could redevelop TSRA. Expect any remaining
precipitation to dissipate after sunset, but MVFR ceilings could
redevelop before sunrise.
&&
.MARINE...
Issued at 1220 AM CDT Thu Jun 18 2026
Strong southerly winds of 20 to 25 knots with gusts of 30 knots
will remain in place over the coastal waters through tonight and
into Thursday and seas of 6 to 9 feet can be expected in the open
Gulf waters. Small craft advisories remain in effect due to these
conditions. Moving into the weekend and early next week, a broad
area of high pressure will build back over the eastern Gulf
waters. Persistent onshore winds of 10 to 15 knots and seas of 2
to 4 feet can be expected from Friday through early next week.

The damage path of a brief EF-0 tornado was identified via high resolution satellite imagery in northwest Harrison County. This tornado caused predominantly damaged to trees over inaccessible areas between West Wortham and McHenry roads. This focused damage path closely aligned with a strong tornado vortex signature that crossed through the area. The tornado apparently lifted as it crossed McHenry Rd as no other damage could be identified as the circulation lifted northward.

A NWS survey team concluded that an EF-1 tornado tracked northeast across Hancock county. Tree damage was widespread along the track including several large trees uprooted and snapped. Minor damage was done to several properties. Additional revisions via high resolution satellite analysis concluded the tornado began west of Standard Dedeaux Rd, north of Rock Hill Dedeaux Rd where it quickly strengthened into an EF-1 tornado and reached its peak width of 275 yards wide. The tornado exited Hancock County, entering Harrison County at Deschamp Road.
Tornado, Harrison

The tornado that began in Hancock County entered Harrison County at Deschamp Road. The tornado then evidently weakened and the damage path become more intermittent until it reached the Wolf River where another swath of trees was rated low-end EF-1. The tornado damage path became intermittent once more after crossing the intersection of Cemetery and Steel Bridge Rd. The tornado then evidently reached its third peak as an EF-1 tornado as it crossed Cemetery Rd and MS Hwy 53 where swaths of trees were damaged and uprooted. The tornado then rapidly dissipated as it continued northeast and it's estimated to have lifted prior to reaching Herman Ladner Rd.
